It seems that the current version of CL110 course, the one based on OpenStack 13.0 is failing to provide the rhel7 image from the first exercise.
I did delete the entire lab, reprovision it and run the instructions from https://role.rhu.redhat.com/rol-rhu/rhz/rhls/course/cl110-13.0/ch01s02 --- but it fails to pass the rhel7 image, mainly there are no images at all.
I am sure that this worked with the older 10.0 version. Is anyone aware about the issue? What is the workaround?
Update: I was able to find a rhel7 qcow2 image on materials.example.com site, download it and attempted to upload the image as admin, but tough luck: I got a nasty generic error with lots of CSS from horizon.
Few hours later: it seems that originally there is only one octavia-amphora-13.0-xxxx image available and an attempt to upload a new rhel7 image will crash the glance service (container), and the direct result is that no images will be returned after that.
Doing a tail on /var/log/containers/glance/api.log does not uncover amu serious errors, only few warnings related to deprecated rabbit* from oslo_messaging. The last message is maybe a little bit more interesting: since image size is ero we will doing resize-before-write for each chunk...
Even docker reports the service as unhealthy after that (sudo docker ps|grep glance) but if I stop the container and start it again there is a surprise: I magically see that a rhel7 image with "saving" status and owned by finance.... which is bit weird because my attempt to upload the image was as admin user, so I would have expected to see the owner as admin.
Clearly something is messed with default lab setup because the first exercise should work after the lab was started.
